MARlNE-RECORD PRESERVER.

` SPECIFICATION forming part of Letters Patent No. 308,708, datedDecember 2, 188 4.

Application filed November 10. 1853.

T 0 all whom t may concern:

Be it known that I, DUNCAN SINCLAIR, of Vai-Nui Oinata, ITellington, NewZealand, have invented a new and useful Improvement in Marine-RecordPreservcrs, ot' which the following is a full, clear, and exactdescription.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in whichssiinilar letters of reference indicttecorresponding parts in all the figures.

Figure 1 is a side elevation ot' my improvement. Fig. 2 is a sectionalside elevation of the saine, taken through the line x m, Fig. l. Fig. 3is a sectional plan view of the saine, taken through the line y y, Fig.2.

The object of this invention is to provide a convenient and reliablemeans for preserving the records of ships wrecked or otherwise lost atsea.

The invention consists in a marine-record preservar constructedwithouter and inner cases connected at their open lower ends by an ann'ularplate,and provided with a cork ling and a separable tube attached at itslower end to a cap-plate screwing into the annular bottom plate, andprovided at its upperend with a screw-cap. The preserver is protectedfrom accidental injury by rubber or rubbercloth sheathing plates appliedto its outer case, and is made more buoyant, and is i'ur` ther protectedfrom accidental injury by cork blocks strung upon a wire and secured tothe outer case and the sheathing-platesby eyerivets, as will behereinafter fully described.

A represents a case,1nade of thin sheet-copper. The top of the case A ismade convex, dome-shaped, or semisphcrical,and the body of the said caseis tapered downward,as shown in Figs. l and 2. The convexed top of thecase A is connected with the body of the said case bya seam, B. The bodyofthe case A is strengthened against injury by sheathing plates D, o1"rubber or rubber cloth, tit-ted to the said case and having their edgesbent outward and sewed to each other by wire, or secured by othersuitable means. rIhe edge of the case A is soldered or otherwise securedair and water tight to an annular plate, E, to the inner side of whichis soldered or other- Wise secured air and water tight the open lowerend of the close-topped tubular case F.

Renewed July 2', 1854. (No model.)

By this construction an air and water tight space is formed between thecases A F,which space is designed to be lled when the preserver is beingniade with cork, R', cut into such a shape as to iit snuglyinto the saidspace, andthus make the preserver very buoyant, so that the preserverwill ioat evtn should the case A be injured or evenV perforated. In theinner edge of the annular plate E is formed a screw-thread, into whichfits the screw-thread formed in the outer surface ot' the tubulariiange` G-, formed upon the' capplate H. A flange "upon the cap-plate Hover` laps the outer side of the annular plate E, and has a packing, I,of leather or other suitable material, interposed between it and thesaid annular plate E, so as to make the joint between tlie said plates HE air and water tight.

To the upper edge of the annular flange G is soldered or otherwisesecured air and wa` ter tight-the lower end of atubular ease, J, theopen upper end of which is closed by ascrewcap, K, the joint being madeain and water tight by a packing-plate, Il, laid upon the upper end ofthe tube J and upon which the cap K is screwed down.

In the bottom of the tubular case J is placed a cork plate, llL-for theroll of records to rest upon.

Around the outside ofthe preserver is placed a ring of corks, N, strungupon a wire or chain, O, which passes through the `eyes of eyerivets l?,secured to the said preserver at the water-line, so as to make thepreserver more buoyant and further protect itfrom accidental injury.

Upon the bottoni ofthe cap-plate His formed a flange or keel, Q, whichhas a hole formed through it to receive a lever for screwing thecapplate H off and on.

The preserver is designed to have a roll of records giving the naine ofthe vessel, the termini of the intended voyage, the names of theofficers and crew, and any other desired information, and an ink-pencilplaced in the inner detachable case, J, so that in case of accident tothe vessel the person having the preserver in charge can take out therecord-roll, write in it a brief account of the accident, reinsert therecord, and throw the preserver overboard, with the expectation that itwill IOO bc picked up by sonic vessel or driven ashore by the wind andwaves, to give an account of the fate of the vessel and crew in case noone should be saved.

The preserver should be kept upon the deck of the vessel, and secured insuch a manner that it cannot become detached by the rolling of thevessel, but will become detached and float should the vessel suddenlysink before the person in charge of the preserver can make an entry andthrow the said preserver overboard.

The top of the preserver is designed to be coated with luminous paint,so that the preserver,when floating in the sea,wi1l be visibleA bynight, and the painted top of the preserver is designed to be coveredand protected by a plate, S, of glass, horn, or other transparentsubstance, as indicated by dotted lines in Fig. l, the edge of which issecured by atlange, C, soldered or otherwise secured to the said top.

The brass plates H and K are designed to havelegibly engraved upon themthe name of the vessel and of the country or port to which the saidvessel belongs, and also the date of the building or launching of thesaid vessel.

Having thus described my invention, I claim as new and desire to secureby Letters Patentm l. -A marine-record preservcr constructedsubstantially as herein shown and described, and consisting` of theouter and inner cases, A. F, connected at their' lower open ends by anannular plate, E, and provided with a cork filling, R, and the separabletube J, attached at its lower end to a cap-plate, H, screwing into theannular plate E, and provided at its upper end with a screw-cap, K, asset forth.

2. In a marine-record preserver, the combination, with the top of thecase A, having a coat of luminous paint, of the transparent covering Sand the iiange C, substantially as herein shown and described.

3. In a marine-record preserver, the combination, with the outer case,A, and the sheathing-plates D, of the cork blocks N, the conmeeting-wireO, and the eye-rivets P, substantially as herein shown anddescribed,whereby the preserver is made more buoyant and is protectedfrom accidental blows, as set forth.
